No need for Fuel management on stock D motor if under 8 pSI boost?
i saw some older post about some that boosted without intercooler and FM and did fine at 7-8 PSI. is that ok for me to do on my D1.6? i'm not doing it for racing ed and boosting every 5 minutes. more for when i need power to move just to get out quick etc..

Nope. Not okay. Don't do it.
If you search around a bit you will see why...

100% not ok.
the motor will not know how to handle the extra air pressure and that's when bad things happen.
at a very minimum run a FMU, and that is not recommended.

Re: No need for Fuel management on stock D motor if under 8 pSI boost? (platinum00)
well my main thing is that i heard FMU tends to eat gas even if your not boosting, is this a true statement? I guess I might have to go this route and get a FMU. remember I will not be boosting like most iof you guys that boost all the time. thast why i'm not thinking about a intercooler. were a good place to get a manifold and DP combo at a cheap price?

Your ecu can't see boost, if the map sensor sees positive pressure in the IM, the ecu goes into limp mode...
No matter how little you are going to boost, you need to have good fuel management.

sure running no managment can be pulled off but for how long? a day, month or even one run on boost could have you with no motor.
if at the least fork over the money for a base tuned uberdata equiped ecu
best saying ever CHEAP - FAST - RELIABLE
PICK TWO

What year is your car? If it is OBD1, you can be running uberdata for the cost of:

Hmm that's OBD2. You'd need a conversion harness + new ecu to use uberdata.
If you just want to run 8psi, get a high pressure inline fuel pump and a 12:1 FMU. Retard your ignition timing 3 or 4 degrees at the distributor.

uberdata is free. hondata is $$.
both of them require a new ECU + conversion harness, larger injectors, and a *recommended* walbro fuel pump.
FMU requires: FMU + missing link/check valves.
You sound like you want to cheap out on stuff (hence your thread title) so I recommend you just use the FMU and check valves.
Even if you run 20psi on the FMU, there is little chance that this will blow my motor

Re: No need for Fuel management on stock D motor if under 8 pSI boost? (ajusaf)
im going to give you this realy good piece of advice, do it right from the start!
if you want to keep a/c and what not go out and buy a a/c compliant turbo kit
if you want to boost for cheap goto homemadeturbo .com
most the time if you want to be cheap about things they arent gonna last long or work all that great
if you have no fabrication skill then you are gonna need to spend money
but to answer your question go to local muffler shop and have then make you a downpipe, they can chop off your oem piping and weld the down pipe to it
i know you probly just want to boost just to boost and not make a carrer out of it, and want to spend the least amount of money on the setup but boost does cost money if you cant do it yourself
im on the low funds situation right now so im using a oem manifold modified to run my T61 and external gate lol but thats for now till i can fab my own mani

Uberdata is a program you use to customize your Honda ECU's fuel and timing maps as well as a few other things. Uberdata the program is free but of course the equipment to run it is not. but even then you still pay a lot less for an Uberdata setup then you would a Hondata setup. With the Hondata you pay for the program, and you'll probably also end up paying for a dealer/tuner to tune your car for you. Uberdata is for the DIY guys out there.

What do you mean use your stock manifold? The CX manifold?
Is that even possible?? Just curious....never heard of it

With 8lbs of boost a stock fuel pump will be just fine. I'm running one with 440cc injectors and it works like a charm.
